  1. Houdini 17 Wishlist

    Hoping the viewport display of volumes can be multithreaded. A 1 billion voxel volume just sits on a single thread trying to redraw.
  2. Is AMD potentially risky? (Threadripper)

    did anyone hear back from SESI if OpenCL CPU will be able to work on the 7900x or TR? I've priced a new build but being limited to the GPU ram for OpenCL is almost a deal breaker.
  3. making color "stick to moving particles ...

    On the popobject just change: /obj/ptScatterGeo/scatter1/ to /obj/ptScatterGeo/ but you're missing the geo for us to properly test it.
  4. Background image

    It's a bug, the $F is lost so you need to set a key frame on the path to make it work. Please submit it As a bug to SESI as it's been there forever and needs to die. thx!
  5. Is AMD potentially risky? (Threadripper)

    plp answer's are vague, non-committal and doesn't use any metrics, best to just wait until someone does real-world tests.
  6. Is AMD potentially risky? (Threadripper)

    @tricecold thanks for testing - that info indicates that the GPU is being used for OCL. Can you please try the following to show all OCL devices available: hgpuinfo -l for example on a MacMini it will show the Intel Chips being available for OCL CPU: hgpuinfo -l OpenCL Platform Apple Platform Vendor Apple Platform Version OpenCL 1.2 (May 26 2017 12:59:48) OpenCL Device Intel(R) Core(TM) i7-2635QM CPU @ 2.00GHz OpenCL Type CPU Device Version OpenCL 1.2 Frequency 2000 MHz Compute Units 8 Device Address Bits 64 Global Memory 16384 MB Max Allocation 4096 MB Global Cache 0 KB Max Constant Args 8 Max Constant Size 64 KB Local Mem Size 32 KB 2D Image Support 8192x8192 3D Image Support 2048x2048x2048
  7. Is AMD potentially risky? (Threadripper)

    yep and it doesn't work for TR or 7900x in our testing. You can test it by setting HOUDINI_OCL_DEVICETYPE=CPU in the environment file. Thanks!
  8. Is AMD potentially risky? (Threadripper)

    they are on Windows but everything we tried didn't work.
  9. Is AMD potentially risky? (Threadripper)

    cool - how did you get it to work? the others tired and it failed. Can you post the hgpuinfo -c for your TR. thanks!
  10. My google-fu is failing so is the there a way to set the a global variable not defined in the .hip file but on the computer? I want to use a network file path on many file cache nodes on Ubuntu and MacOs. Ubuntu mounts with /mnt/ whilst MacOs mounts with /Volumes/. Currently I'm setting $NETWORKPATH in the Variables gui window as the full path and when I open the file on each platform I rset the path to be correct manually.
  11. you're overwriting the arnold stuff with the redshift path & Houdini path. try something like adding a : HOUDINI_PATH = "C:\Users\screenglow\htoa\htoa-2.1.3_rcca6014_houdini-16.0.705\htoa-2.1.3_rcca6014_houdini-16.0.705;&:C:\Users\screenglow\htoa\htoa-2.1.3_rcca6014_houdini-16.0.705\htoa-2.1.3_rcca6014_houdini-16.0.705;&" Ref: https://stackoverflow.com/questions/21131590/how-to-add-multiple-path-in-path-variable-linux
  12. Is AMD potentially risky? (Threadripper)

    If OCL CPU worked on TR/7900x you should get ~50% increase on the grain solver.
  13. Is AMD potentially risky? (Threadripper)

    Lets wait to test it before saying it will Also Threadripper is the start of the new line of AMD HEDT, so what comes next will be interesting, i.e. more ram support. Also EPYC is out there for serious builds.
  14. the main issue is that if you don't scale your scene down from Maya then you are computing in less floating point precision in Houdini as a lot of operations are still in 32bit. FP precision is logarithmic in nature and is most dense >-1<1
  15. Is AMD potentially risky? (Threadripper)

    Anyone running TR or 7900x on Linux or is this all for Windows? For Ryzen it's almost impossible to get the cpu temps in the 4.10 kernel whilst the 4.11 allows it the Nvidia drivers are borked there.
  16. I think your approach should be to use pscale and pointRelax, haven't tested it but worth a try. http://www.sidefx.com/docs/houdini/nodes/sop/relax
  17. Is AMD potentially risky? (Threadripper)

    the 7900x looks excellent but am concerned under continuous load that the heat will be too much. An overnight Pyro sim or Mantra would be a good starting point to see if the cooling works well and the performance stays up.
  18. Renting a pro tier workstation in Vancouver

    Not an answer but in general pro gear costs as much to rent for a month or two as building your own rig.
  19. Tree and Foliage Tools

    Looks cool - do you have a sample of a final tree available to check out?
  20. Unable to load HFS OpenCL platform.

    We can only guess because you aren't supplying any hardware details. Either you should use the cpu or a discrete GPU for the OpenCL. So put either of these into your env file: HOUDINI_OCL_DEVICETYPE=CPU HOUDINI_OCL_DEVICENUMBER=1 if that doesn't help then use hgpuinfo -l to list all the available OpenCL devices.
  21. 1. turn on webcam. 2. record. 3. repeat.
  22. The need for {} in path values

    @ikoon hip attached. Fields.hipnc
  23. Is AMD potentially risky? (Threadripper)

    It should be faster on most modern GPUs but they can't access the CPU ram and therefore a generally limited to smaller sims. I'm hoping for Gtx 980 speed on the TR/7900x.
  24. The need for {} in path values

    You can create a linked field that displays the expression evaluated. Makes it easy to see valid delimters.
  25. Is AMD potentially risky? (Threadripper)

    major bummer - oh well at least the CPU is fast enough anyways.
